End face sealing structure for mechanical product

The invention discloses an end face sealing structure for a mechanical product. The end face sealing structure comprises a sealing ring and a sealing seat body or a product sealing component body. An annular sealing groove is formed in the sealing bonding face of the sealing seat body or the product sealing component body. The sealing ring is embedded into the annular sealing groove. The section of the annular sealing groove is of a trapezoidal frame with a small groove opening and a big groove bottom. The sealing ring is an O-shaped sealing ring. The problem that the sealing ring breaks away from the sealing groove or drops out of the sealing groove is solved effectively, and besides the sealing effect is further improved. 本发明公开了种用于机械产品的端面密封结构，包括密封圈和密封座体或产品密封构件本体，密封体或产品密封构件本体的密封结合面上设置环形密封槽，所述密封圈嵌装在环形密封槽内，所述环形密封槽的截面槽口小、槽底大的为梯形结构，所述密封圈为O型密封圈；有效地解决了密封圈容易脱离密封槽或掉出的问题，而且进步提高了密封效果。
